With its ultra-compact design, it features ¼” TRS inputs and outputs for seamless integration into your audio setup, ensuring high-quality sound without the buzz. Weighing only 0.2 kg and measuring 2.36” x 4.09” x 1.38”, it's the perfect travel companion for audio professionals. ## Description Almost all 60Hz AC hum is caused by ground loops that act like radio antennae (loop antenna). The Hum Eliminator completely eliminates this by breaking the ground loop, making it impossible for the signal lines to pick up the AC hum and noise in the first place. Unbalanced lines are more susceptible to picking up electrical noise and RF interference than balanced lines - the longer the unbalanced cable, the greater the chance of a problem. Using this device to connect two pieces of equipment is one of the most cost-effective ways to convert between unbalanced signals and true balanced signals. Automatically Translates Signal Voltages to Match Difference in Ground Potentials. Review: Works great! - Compact and perfect for my install. I had a rack of older unbalanced synths I needed to connect to my mixer using a balanced snake. I had a ground loop issue causing hum on 4 synth units plugging directly into the TRS snake that was going to balanced returns on the board. The accumulative hum was bad and annoying, that was a total of 8 channels of hum. I grabbed one of my much more expensive hum eliminators ($80.00) and it removed the hum in one unit. I needed 4-2 channel units and 4 of those would have cost $320.00. These units would only cost roughly $60.00 for 8 channels. I ordered the Pyle Hum Destroyers on desertcart and they arrived the next afternoon. I did a side by side audio comparison test with the more expensive unit, and the results were the same. Zero hum, and in addition like the more expensive unit the Pyle also automatically converts the unbalanced output connections of the synths to balanced out to the board. I found that using a TS cable from the synth actually works better than using a short TRS patch cable which I tried first. The 2 ft. TS cables from the rack mounted synth to the Hum Destroyer worked best, the TRS cable still had a very small amount of hum most likely due to the internal unbalanced jack configuration of the older synth. These were JV1080's. So, unbalanced TS from JV to Hum Destroyer, then out of the Hum Destroyer via TRS balanced snake to the board, hum completely gone. The added benefit is that the Pyle size is more compact, and fits more easily in the back of the rack. I opened one unit and although the construction is less robust than the expensive unit, there are indeed two isolation transformers and a circuit board in an all metal box. They will just stay stationary in the rack so I'm not worried about how they stand up to road abuse. Great value for the money. Used for the correct application these will remove your hum. Review: Worked Perfectly - I moved recently and changed my computer and keyboard setup. I was getting a persistant low level hum through my speakers. I tried switching the cords out to balanced ones, plugging everything in on the same outlet, but nothing worked. It wasn't bad, just annoying. I did some searching and came accross this unit. It wasn't very expensive and the reviews were mostly positive, so I decided to give it a try with pretty low expectations. When it arrived, I patched it in between my Steinberg UR44 and the speakers and low and behold the hum was gone. I have had it plugged in for about a month now and the hum is nowhere to be... heard. Highly recommend. ## Features - Removes AC Hum Noise - (2) 1/4-Inch TRS Inputs and Outputs for 2-Mono or 1 Stereo Signal - Breaks Ground Loops Safely - Automatically Converts Unbalanced to Balanced Signal Without Any Signal Loss - Maintains Highest Sonic Quality - High-Performance Ultra-Compact Design - High-Quality Components and Exceptionally Rugged Construction ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00BARTW3I | | Antenna Location | Radio | | Battery Capacity | 1.5 Volts | | Battery Weight | 10 Grams | | Best Sellers Rank | #8,331 in Musical Instruments ( See Top 100 in Musical Instruments ) #4 in Equalizers & Feedback Controllers | | Brand | Pyle | | Customer Reviews | 3.8 out of 5 stars 826 Reviews | | External Testing Certification | NΓ£o AplicΓ‘vel | | Global Trade Identification Number | 00068888738286 | | Item Dimensions | 2.36 x 4.09 x 1.38 inches | | Item Type Name | Pyle | | Item Weight | 0.2 Kilograms | | Manufacturer | Sound Around | | Model Name | PHE300 | | Model Number | PHE300 | | Recommended Uses For Product | Radio | | Reusability | Single Use | | UPC | 068888738286 | | Unit Count | 1.0 Count | | Voltage | 12 Volts | | Warranty Description | 90 days. | ## Product Details - **Brand:** Pyle - **Battery Capacity:** 1.5 Volts - **Recommended Uses For Product:** Radio - **Unit Count:** 1.0 Count - **Voltage:** 12 Volts ## Images ![PYLE-PRO Compact Mini Hum Eliminator Box-2 Channel Passive Ground Loop Isolator, Noise Filter, AC Buzz Destroyer, Hum Killer w/ 2 1/4-Inch TRS Input and Output for 2 Mono /1 Stereo Signal - Image 1](https://m.media-amazon.com/images/I/51j0XVXVe4L.jpg) ## Available Options This product comes in different **Pattern** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great! *by S***N on July 14, 2019* Compact and perfect for my install.

No luck. The noise became much louder, even on lower volumes. Don't know why that would happen, but whatever this device is designed to do, it's not working for in my setup. Here's what I did. Plugged in the acoustic-electric in an Input using a TS cable. Used a TRS cable from the Output to my practice amp (I also tried it with my Focusrite audio interface). The low volume noise without the Hum Eliminator became loud with it. This box may reduce certain types of noise in other situations, but it made mine worse. Interestingly, I have a Fender Mustang Micro headphone amp that does not work at all with the piezo pickups in my acoustic-electric. However, it works great with the Pyle box in between the acoustic-electric and the Mustang Micro. ## Frequently Bought Together - PYLE-PRO Compact Mini Hum Eliminator Box-2 Channel Passive Ground Loop Isolator, Noise Filter, AC Buzz Destroyer, Hum Killer w/ 2 1/4-Inch TRS Input and Output for 2 Mono /1 Stereo Signal - Pyle Premium Direct Injection Audio Box - 2.36" x 4.09" Passive DI Unit Hum Eliminator w/ Input Attenuator to Connect Guitar & Bass, 1/4'' Impedance Transformer Connector to Balanced & Unbalanced XLR --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ro/products/3945350-pyle-pro-compact-mini-hum-eliminator-box-2-channel-passive](https://www.desertcart.ro/products/3945350-pyle-pro-compact-mini-hum-eliminator-box-2-channel-passive) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-06-08*
